  • Serious adverse events include anaphylaxis and acute disseminated encephalomyelitis (ADEM).
  • Surveillance for AEFIs has been implemented globally since the introduction of acellular vaccines.

Guideline-Based Recommendations

Diagnosis

  • Monitor for mild, moderate, and serious AEFIs post-vaccination.

Management

  • Provide supportive care for mild and moderate AEFIs.
  • Investigate serious AEFIs such as anaphylaxis and ADEM.

Monitoring & Follow-up

  • Systematic surveillance for AEFIs should be maintained.

Risks

  • Infants under 6 months are at higher risk for hypotonic hyporesponsive episodes.

Patient & Prescribing Data

Infants receiving DTaP and Tdap vaccines.

Vaccination is associated with a range of mild to serious adverse events, necessitating careful monitoring.
